Abstract


Energy and the environment in recent years, the increasing influence of the human and social development, as soon as possible to improve the living environment of mankind growing louder and louder. Pure electric vehicles as a new energy vehicles, has zero emissions, low noise advantages, more and more attention of the world, is known as a green car. Technology roadmap in a lot of the research and development of electric vehicles, electric wheel electric vehicle drive system has gradually become a novel research direction of the electric car, it is because of the the ideal control features and a wide range of application prospects by academic and engineering attention. Domestic, is still at its infancy. In this paper, four-wheel independent drive system as the research object around the the DSP plus single-chip multi-CPU control system-related research, design, and analysis. Select the optimal control strategy, so that the four-wheel independent drive electric vehicle has the best power and handling stability. This article begins with comprehensive research progress of the development background of electric vehicles and electric vehicles at home and abroad. With relatively more in today's electric vehicles on several motor characteristics, combined with the characteristics of the electric vehicle, pointed out the advantages of a permanent magnet brushless DC motor in electric vehicle applications. Then introduced the structure and operating principle of the drive motor, derived a mathematical model of the drive motor, and analyzed the characteristics of several motor control strategy. Secondly, four independent drive technical characteristics, combined with this paper drive motor torque control strategy, the control strategy of torque and slip rate of the vehicle control system. And a detailed analysis of the characteristics of the electronic differential technology, and propose specific solutions for the electronic differential technology. Again, integrated above control strategy proposed for the upper end of the controller, a DSP chip AVR microcontroller as the lower end of the controller, the control of multi-CPU system hardware circuit. Main modules specific analysis and design, and introduced the software process. Finally, the fuzzy control used in the control system, combined with four independent drive control strategy, and effective control of the slip rate of the system, in order to make electric vehicles having the best power and steering stability. Through MATLAB simulation results show that: the fuzzy control the use of slip rate control in the the expected ideal range, to achieve the design requirements.
